* Input: ALPS - add interleaved protocol support (Dell E6x00 series)Sebastian Kapfer2009-12-16
| | | | | | | | | | | | | | | | | | Properly handle version of the protocol where standard PS/2 packets from trackpoint are stuffed into middle (byte 3-6) of the standard ALPS packets when both the touchpad and trackpoint are used together. The patch is based on work done by Matthew Chapman and additional research done by David Kubicek and Erik Osterholm: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/296610 Many thanks to David Kubicek for his efforts in researching fine points of this new version of the protocol, especially interaction between pad and stick in these models.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b7802c5c1ea ("Input: psmouse - use boolean type") caused the synaptics_hardware variable to be completely useless, as it is constantly set to 'true' throughout the whole psmouse_extensions(). This was caused by the following hunk in the commit in question - int synaptics_hardware = 0; + bool synaptics_hardware = true; which is wrong and causes driver to issue extra reset when falling back to bare PS/2 protocol.

* | Input: ALPS - add support for touchpads with 4-directional buttonMaxim Levitsky2009-11-20
| | | | | | | | | | | | | | | | | | | | | | | | The touchpad on Acer Aspire 5720, 5520 and some other Aspire models (signature 0x73, 0x02, 0x50) has a button that can be rocked in 4 different directions. Make the driver to generate BTN_0..BTN_3 events in response. The Synaptics driver by default maps BTN_0 and BTN_1 to up and down, so there should be no visible changes with the old setup that generated BTN_FORWARD and BTN_BACK (also mapped to up and down).

* Input: libps2 - additional locking for i8042 portsDmitry Torokhov2009-09-18
| | | | | | | | | | | | | | | | | The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

* Input: hgpk - forced recalibration for the OLPC touchpadPaul Fox2009-08-05
| | | | | | | | | | | | | | | | | | | The OLPC XO laptop incorporates a combination touchpad/tablet device which unfortunately requires frequent recalibration. The driver will force this automatically when various suspicious behaviors are observed, and the user can recalibrate manually (with a special keyboard sequence). There's currently no way, however, for an external program to cause recalibration. We can not use the reconnect capability which is already available in /sys because full reset of the touchpad takes 1.1 - 1.2 secons which is too long. This patch creates a new node in /sys which, when written with '1', will force a touchpad recalibration; no other writes (or reads) of this node are supported.

* Input: appletouch - improve finger detectionJeremy Huddleston2009-06-03
| | | | | | | | | | | | | | | | | The appletouch driver is prone to reporting multiple fingers when only one is pressing. The appletouch driver queries an array of pressure sensors and counts local maxima in pressure to determine the number of fingers. It just does this on the raw values, so a data stream like: 0 100 250 300 299 300 250 100 0 actually registers as 2 fingers. This patch updates the logic to ignore small dips in pressure that are less than the threshold.

* Input: psmouse - ESD workaround fix for OLPC XO touchpadZephaniah E. Hull2009-05-15
| | | | | | | | | | | | | | It appears that when the XO touchpad unit resets from ESD, it sends AA AA instead of AA 00, the psmouse-base code handles the case of AA 00 by triggering a serio reconnect for the port, causing a full reprobe of the device. Testing with OFW shows that this is likely to solve the problem, so the attached patch simply expands the existing test to also catch AA AA.

| | | | | | | | | | | When we get a relative packet from trackpoint (when we deal with touchscreen/trackpoint combo) we should not send events for the device corresponding to touchscreen as it confuses evtouch driver (it looks like it keeps previously reported absolute coordinates and the cursor stays in the same place).

Reading back the register afterwards reveils that the absolute mode bit is not set as if masked out by the touchpad firmware. Always read back register 0x10, make sure that for hardware version 1 the absolute mode bit is actually set and fail otherwise.
